Question
Savita covered 180 km distance in 10 hours. The first part of her journey she covered by bus, then she hired an auto. The speed of bus and auto is 20 kmph and 15 kmph respectively. The ratio of distances covered by bus and auto is:
Answer: Option D
:
D
Average speed of Savita over the complete journey = 18010 = 18 kmph.
This means auto took 2/5 of the total time and bus took 3/5 of the total time. So, the ratio of the time taken (bus: auto) = 3: 2.
So, ratio of distance covered = 3×20:2×15 = 60 : 30 = 2 : 1.
Hence option (d)
